sorry if i did something wrong.

oh so sorry, i used optifine and you guys don't like it. ok.

@kenijey

This is not an issue with Optifine; This is most likely a misconfiguration of a mod that adds mobs to the game.

Passive mobs are generally spawned in groups, and a minimum and maximum amount can be specified to add some randomness to the spawning. If the maximum is set to a lower value than the minimum, then an erroneous value is passed to java.util.Random which results in this crash.

then how about this crash

same thing? it crashed on ruins mods side too. i hope it's the same thing..
and ah, i delete and retweak configs everytime if i update a mod, it's very sad for me.
really would like to know what's wrong.

hello @srs-bsns , thank you very very much. i just forgot to disable pig spawn in Animania mod config. i tweaked the maximum spawn rate to 0 but i forgot to disable it completely. thanks you!
